Safe to use an impact wrench on the scissor jack that comes with the car?

[Howard]

Anybody know?

I don't see why not - all it's doing is turning a screw...similar to using an impact on a spring compressor.

Sure, but I wouldn't expect it to last too long.
Examine the construction of the thing-they don't appear like they will sustain multiple impact hits.
As for the spring compressor comparison-different steel composition-they're not designed for that.

I use my Snapon 18V impact on my travel trailers 5K scissor jacks :biggrin: Sure beats the heck out of using the little crank handle...

If it was me, I'd make sure the threads were lubed up good. It obviously will be turning a lot faster than it would if worked by hand. I think if you made a habit of doing this, the jack would quickly become useless. I don't think the steel is of high enough quality and/or heat treated properly for this kind of use on a regular basis.

But, sounds as though Bartman is having good luck...

I DID mean on a regular basis that I would say no--to save your ass when you have a flat have at it-I would use both-electric till contact and hand crank it to get it off the ground.

If I don't need to have more than one wheel on the ground at a time, I hate having to use a regular jack since I have to jack my car up on a point that's not reinforced.

Sure, just do it slowly and don't go full out on the trigger.

A 5 ton RV scissor jack is only similar to the scissor jack found in a car for changing tires in that both are scissor jacks by design. Other than that, Bartman's scissor jack he mentioned is in no way like a car's.

Yea I guess they are just similar in design but not as heavy duty like those on my RV...? Also I really only use the impact to run them up and down but use a long handle 1/2" drive ratchet & 3/4" socket to do the real adjustments and I lube them quite often with a teflon spray...
